Syria Conflict: Islamic State ‘Committed War Crimes’
Islamic State militants have committed “mass atrocities” in Syria, including the recruitment of children as fighters, the United Nations says.
Investigators have also accused the Syrian government of using chemical agents in eight separate incidents in western Syria this year.
Islamic State (IS), which now controls areas of Syria, is one of the groups fighting President Bashar al-Assad.
Some 200,000 have died since the conflict began in early 2011.
